Custom Error Pages:

When someone visits a website or area there is always a possibility that the link they followed may be out-of-date or broken or they may have typed the address in wrongly. When this happens an error page is displayed.

By default a standard error page is received. This does not give the user much information about the area they were in or any details of who they should contact.

A custom error page allows you to specify a set of links the visitor could try, as well as a contact for help. If a site is re-developed and pages are moved/renamed this ensures that visitors will receive some useful local information and continue to explore the site.
